SPECIFICATION forming part of Letters Patent No. 397,886, dated February 19, 1889. Application filed April 1l, '1887- Serial No. 234,385. (No model.)

To @ZZ whom, it 71mg/ concern:

Be it known that I, HENRY R. ALBRECHT, a citizen of the United States, residing at Moline, in the county of Rock Island, State of Illinois, have invented certain new and useful Improvements in (lar-I-Icaters, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to car-heaters, and more particularly to that class thereof in which water is utilized to extinguish the fire in case of accident.

Among the objects of the invention is to provide a heater which in case of accident (such as collision or ovcrtinfning of' the ear, dac.) will automatically assume such position as to permit ot" the inflow of water, whereby the fire will be extinguished, and in which the tire will be entirely cut of'f from falling out of the stove into the debris and setting .fire thereto.

Vith these general objects of the invention in view the saine consists in certain features of construction, hereinafter described, and particularly pointed out in the claims.

Referring to the drawing, which is a vertical central partial section of a car-heater constructed in accordance with my invention, A represents the bottom or floor of a car, which is recessed to receive a water-tank, B, set therein, which tank is surrounded by a jacket, B', between which and the tank is a filling of sawdust or other material, B2, for the purpose of preventing the water in the tank from freezing. An opening, B3, provided with a valveseat, is formed in the bottom of the tank and jacket, and adapted to receive a valve, B", to which is iixed a rod, screw-threaded in and passing through the top of the tank, and provided with a suitable hand-wheel for controlling the valve. By means ot' this valve water admitted through the opening or forced in through the opening B may be passed off.

Mounted upon and communicating with the tank B through an opening', B, therein is an outer casing or cylinder, C, formed with a dome, C', a fuel-poke, C2, and an uptake,

At each side of the cylinder, near its bottom and diametrically opposite each other, are 'formed laterally-projecting lugs C5, which are perforated for the reception of bolts C,

which i'orm bearings for and pass through holes formed near the lower ends of weighted levers D, which are laterally bent at their lower ends to form catches D.

- Mounted on the lower or catch ends of the levers D by means of an annular flange, E', or it may be simply diametrically-located lugs under which t-he ends of the levers take, is an annular casting, E, formed to it the base of the cylinder C, and with an opening, E2, formed as a valve-seat, into which a valveplate, E3, is adapted to be seated.

Mounted upon the casting E-in this instance upon the annular flange E thereof-is the flre-cylin der F, which is formed with openings F F2, communicating with the fuel-poke and uptake in the outer cylinder. Lateral guiding-lugs Fi? are formed on the iire-cylinder, so that said cylinder may freely slide within the outer cylinder or casing, C. An annular flange, F4, is formed in the iire-cylinder F, upon which is mounted the grate and ire box FG. interposed between the grate F5 and valve-plate E3, an d mounted upon the latter, is an ash-pan, FT.

For the purpose of permitting of a free eirculation of products of combustion into the cylinder C, perforations F8 are formed in the top of the fire-cylinder F, through which products of combustion may pass into the outer cylinder and into the dome C.

The operation of the invention will be readily apparent from the above description, in that any sudden lateral jar, such as caused by a collision, will cause the weighted levers D to oscillate upon their pivots and be withdrawn from under the flanges E formed on the annular casting E, thus allowing the cylinder F and its contents containing the iire to fall through the opening BG into the watertank, whereby the fire will be immediately extinguished.

Incase the car is derailed, and consequently overturned or thrown upon its side, the valveplate E3 will fall from its seat in the annular casting E, and water will be allowed to pass through the opening E2 into the fire-cylinder. In this instance the fire-cylinder falls to the opposite position-namely, toward the dome of the cylinder C-thus practically closing all communication with the outside, either through the uptake, fuel-poke, or other doors IOO or openings formed for draft, removing the ashes, die. The fire thus wholly maintained within the inner cylinder is quicklyv and positively extinguished hy the iiow of water from the tank I thereon.

Having thus `[i'ully described my invention and its operation, what I Claim l. In aear-heater, the Combination oi' a water-tank havingl an outer heating-eyli nder mounted thereon provided with a fuel-poke and uptake, with a lire-eylin der mounted :for longitudinal movement in said heating-cylinder, and provided with apertures or openings communicating with said fuel-poke and up- I with the castingl l, having the opening E2,

take, wherelrxT by reason of said longitudinal movement olf the fire-Cylinder the communication maT he broken, substantially as specitied.

f2. In a ear-heater, the eomhinatitni of an outer heating' cylinder having,r pivoted weighted levers projecting therein, said cylinder being' mounted upon and Communicatingl with a water-tanl1', with an annular eastsenese Outer heating-cylinder having loosely-pivoted weighted arms, as l), projecting therein, with an annular Casting provided with a flange mounted on said arms, and a {ire-cylinder mounted on said casting and provided with perlinations at its top, substantially as speei hed.

i, The eylinder C, havingl the lugs C and holt C and weighted arms D, in combination formed with a valve-seat, and the valve-plate Ilf, substantially as specified.

In testimony whereof I a Flix my sign ature in presence ot' two witnesses.
